Microsoft is warning XP users to avoid using a hack that allows continued security updates of the operating system, despite the fact that the company put an end to XP support in early April.  

In a statement released to ZDnet on Monday, the company said: 

We recently became aware of a hack that purportedly aims to provide security updates to Windows XP customers. The security updates that could be installed are intended for Windows Embedded and and Windows Server 2003 customers and do not fully protect Windows XP customers.

Windows XP customers also run a significant risk of functionality issues with their machines if they install these updates, as they are not tested against Windows XP. The best way for Windows XP customers to protect their systems is to upgrade to a more modern operating system, like Windows 7 or Windows 8.1." 

The hack capitalizes on the fact some users are looking for a workaround to keep their XP computers secure in the absence of updates from Microsoft.
